Image generated from 3 photos taken with my E-P1 17mm lens, then the views corrected for two different types (not including barrel distortion) of views.
View on the left is a rectilinear projection with no vertical references defined.
View on the right is rectilinear with vertical references, producing what is more commonly referred to as an "architectural view" (or axonometric, or planometric in this case).
